所述连接杆与所述中部、所述连接杆与所述端部的连接处形成铰链结构。 具体地，中部与左侧的连接杆形成第一铰链，而与右侧的连接杆形成第二铰链，该第一铰链和第二铰链呈对称设置；另外，左侧的连接杆与左侧的端部形成第三铰链，而右侧的连接杆与右侧的端部形成第四铰链，该第三铰链和第四铰链呈对称设置。
所述推杆的两推杆端部的中心轴线之间的距离与所述连接杆两端的铰链结构之间的距离相等。。
所述中部和所述端部为独立的三个部件，所述推杆本身形成对称的铰链结构。
本发明还提供一种夹持装置，所述夹持装置包括上述的锁止机构。

具体实施方式
下面结合附图，给出本发明的较佳实施例，并予以详细描述。
图1是根据本发明的第一实施例的支架系统的爆炸图，其中，该支架系统包括可拆卸连接的设备支架1和安装基座2。其中，该设备支架1包括相互连接的夹持装置11和悬臂12，该夹持装置11用于固定待夹持设备，例如手机，该悬臂12从该夹持装置11的背面开始延伸。该悬臂12的与夹持装置11相对的自由端的底部具有设备支架凹槽结构13，相对应地，该安装基座2的顶部具有安装基座突出结构21，该设备支架凹槽结构13和安装基座突出结构21相互配合，从而可以将设备支架1和安装基座2组装在一起。可选地，图1的实施例中的支架系统还包括有独立的闷盖3，该闷盖3的底部具有闷盖凹槽结构31，该闷盖凹槽结构31和安装基座突出结构21相互配合可以将闷盖3和安装基座2组装在一起。
图2是根据本发明的第一实施例的车载支架系统的设备支架1的夹持装置11的爆炸图，其中，该夹持装置11包括滑动配合的固定夹持元件111和运动夹持元件112。其中，固定夹持元件111包括固定夹持元件本体1111和从该固定夹持元件本体1111的一端延伸出的固定爪1112，运动夹持元件112包括运动夹持元件本体1121和从该运动夹持元件本体1121的一端延伸出的运动爪1122，固定夹持元件本体1111相对于运动夹持元件本体1121相对滑动，从而通过彼此相对的固定爪1112和运动爪1122之间的距离来限定待夹持设备的高度，相对应地，运动夹持元件本体1121的正面形成支承面1123，待夹持设备直接抵靠在支承面1123上。固定夹持元件111和运动夹持元件112组装成型后，固定爪1112与支承面1123之间的夹角优选为85°，运动爪1122与支承面1123之间的夹角同样优选为85°，如此形成的梯形空间(由固定爪1112、运动爪1122与支承面1123形成的空间)限定了待夹持设备被固定后的自由度，同时保证了尽可能少地对待夹持设备的显示内容造成遮挡。在一个优选的实施例中，运动爪1122的远离运动夹持元件本体1121的端部具有朝向内侧的凸起结构1124，同理，固定爪的相应端部同样可具有凸起结构，如此在极端工况下进一步保证待夹持设备被夹持的可靠性。另外，固定爪1112和运 动爪1122的彼此相对的表面上可设有弹性垫片113，当待夹持设备被夹持于固定爪1112和运动爪1122之间时，该弹性垫片113能够为待夹持设备提供缓冲并获得横向的摩擦锁止，从而防止其从夹持装置11内脱出。在图2中，由于固定爪1112示出为板状，其相对应的弹性垫片113示出为片状，而由于运动爪1122示出为彼此大致平行延伸的一对条状延伸部，其对应的弹性垫片113示出为条状，又由于该条状延伸部示出为具有沿其长度延伸的沟槽，相对应的弹性垫片113具有容置于沟槽内的容置部，从而将弹性垫片113固定于运动爪1122。应该理解，只要能够实现提供缓冲并夹持设备的目的，任何其他形状的固定爪、运动爪和弹性垫片均是可行的。
固定夹持元件111的背面设置有卷簧机构114、开关机构115和锁止机构116，其中，该卷簧机构114为固定夹持元件111的固定爪1112和运动夹持元件112的运动爪1122提供促使其相互接近的牵引力，从而夹紧待夹持设备；该开关机构115在外力的作用下在第一状态和第二状态之间运动；该锁止机构116在开关机构115的作用下相应地在锁止状态和解锁状态之间变化。
具体地参见图2可知，该卷簧机构114包括卷簧心轴1141、卷簧1142、卷簧开口1143和卷簧挂钩1144，其中，该卷簧心轴1141固定于固定夹持元件111的背面，卷簧1142套设于卷簧心轴1141的外侧，卷簧开口1143在固定夹持元件本体1111的中部贯穿该固定夹持元件本体1111的正面和背面，而卷簧挂钩1144设置于运动夹持元件本体1121的背面。如此，卷簧1142的具有开口的一端从卷簧开口1143伸出从背面延伸到正面，并挂在运动夹持元件本体1121的卷簧挂钩1144上，从而利用卷簧1142的收缩力使固定夹持元件111和运动夹持元件112之间具有弹簧预紧，借助该卷簧力使运动夹持元件112能够始终向上回弹，保证待夹持设备始终与固定爪1112及运动爪1122接触。应该理解，该卷簧力的具体提供方式并不局限于此，卷簧等的设置位置可以根据需要进行调整，只要能够在固定夹持元件111和运动夹持元件112之间提供回弹力即可。
该开关机构115包括弹簧碰锁1151、按钮导轨1152、复位弹簧1153、锁定控制杆1154和控制按钮1155，其中，该弹簧碰锁1151与按钮导轨1152相对固定并且固定于固定夹持元件111的背面；锁定控制杆1154和控制按钮1155相对固定并且可相对于固定夹持元件111移动；复位弹簧1153设置于锁定控制杆1154和固定夹持元件111之间，从而为锁定控制杆1154提供回复力。具体地，锁定控制杆1154具有容纳孔，弹簧碰锁1151与按钮导轨1152均容 置于该容纳孔中，且锁定控制杆1154上具有导杆，按钮导轨1152上具有导轨，导杆导轨相互配合实现锁定控制杆1154与按钮导轨1152之间的相对运动。另外，锁定控制杆1154具有碰锁锁舌1157(参见图3)，该碰锁锁舌1157在该容纳孔内延伸并与弹簧碰锁1151配合。
图3示出了根据本发明的第一实施例的车载支架系统的设备支架的夹持装置的锁止机构，该锁止机构116包括锁止元件1161和推杆1162，其中，锁止元件1161包括中部1163和设置于该中部1163两侧的端部1164，该中部1163的两个角分别通过四根连接杆1165连接于端部1164。连接杆1165与中部1163、连接杆1165与端部1164的连接处共形成八个铰链结构1166，在图3中，左侧的端部1164、左侧的相对的两连接杆1165和中部1163的左侧形成一个左平行四连杆结构；而右侧的端部1164、右侧的相对的两连接杆1165和中部1163的右侧形成一个右平行四连杆结构；即该锁止元件1161通过连接杆1165与所述中部1163和端部1164配合形成对称的两平行四连杆结构，从而使得锁止元件1161的中部具有自由摆动的自由度。中部1163、端部1164和连接杆1165共同限定镂空部，两根推杆1162容置于该镂空部内，从而使得推杆1162可以随之发生摆动。具体地，每根推杆1162具有相对设置的两推杆端部，该推杆端部呈圆柱体形，镂空部包括有C形半孔，该推杆的推杆端部与C形半孔形成转动配合，推杆1162的两推杆端部的中心轴线之间的距离d与所述连接杆两端的铰链结构之间的距离D相等，参见图6，因而能够与平行四连杆结构一起平行摆动。另外，固定夹持元件111的背面固定有从其延伸的彼此相对的两端板，该端板的下端具有彼此相对的两个锁止元件开口1113(参见图2)，锁止元件1161的两个端部1164分别从该两个锁止元件开口1113伸出，从而通过该锁止元件开口1113来限制该锁止元件1161的端部1164纵向上的移动，如图4-图5所示。另外，该锁止元件1161的两个端部1164的最远端具有锁止齿条1168，而运动夹持元件112具有运动夹持元件齿条1125，该锁止齿条1168与该运动夹持元件齿条1125配合，如图4-图5所示。
图3除了示出了根据本发明的第一实施例的车载支架系统的设备支架的夹持装置的锁止机构，还示出了开关结构的锁定控制杆。其中，开关机构115的锁定控制杆1154的正面上设有定位销1156，而锁止机构116的中部1163上设有贯穿的定位孔1167，从而通过定位销1156和定位孔1167的配合实现开关机构115和锁止机构116之间的联动，即随着开关机构115在外力的作用 下在第一状态和第二状态之间运动；该锁止机构116在开关机构115的作用下相应地在解锁状态和锁止状态之间变化。
开关机构115和锁止机构116的解锁状态如图4所示，控制按钮1155的顶面高于固定夹持元件111的顶面：弹簧碰锁1151将碰锁锁舌1157顶出，锁定控制杆1154在复位弹簧1153的作用下脱离束缚而远离弹簧碰锁1151移动，从而带动锁止元件1161的中部1163移动。此时，由于锁止元件1161的端部1164受到锁止元件开口1113的限制而只能横向向内收缩(参见图6)，锁止齿条1168与运动夹持元件齿条1125脱离，从而解除锁止运动夹持元件112。
开关机构115和锁止机构116的锁止状态如图5所示，控制按钮1155的顶面与固定夹持元件111的顶面齐平：弹簧碰锁1151将碰锁锁舌1157固定在弹簧碰锁1151的内部，锁定控制杆1154向下移动，带动锁止元件1161的中部1163随其移动。此时，由于锁止元件1161的端部1164受到锁止元件开口1113的限制而只能横向向外扩张(参见图7)，锁止齿条1168与运动夹持元件齿条1125啮合，从而将运动夹持元件112锁止。
图8示出了根据本发明的第二实施例的车载支架系统的设备支架的锁止机构，该锁止机构216包括锁止元件2161和推杆2162，其中，锁止元件2161包括中部2163和设置于该中部2163两侧的端部2164，该中部2163和端部2164为独立的三个部件。在本实施例中，中部2163包括四个C形半孔，每个端部包括两个C形半孔，八根推杆2162中的每根推杆均具有相对设置的两推杆端部，该推杆端部呈圆柱体形，每根推杆2162的推杆端部分别与中部2163和端部2164的C形半孔形成转动配合，从而利用推杆2162本身形成八个铰链结构2166，在图9中，左侧的端部2164、左侧的两推杆2162和中部2163的左侧形成一个左平行四连杆结构；而右侧的端部2164、右侧的两推杆2162和中部2163的右侧形成一个右平行四连杆结构；即该锁止元件2161通过推杆2162与中部2163和端部2164配合同样形成对称的两平行四连杆结构，从而使得锁止元件2161的中部具有自由摆动的自由度。另外，该锁止元件2161的中部2163同样具有与锁定控制杆1154配合的定位孔2167，而锁止元件2161的两个端部2164的最远端同样具有锁止齿条2168。
锁止机构216的解锁状态如图9所示，锁止元件2161的中部2163在锁定控制杆1154的作用下纵向向上移动，由于锁止元件2161的端部2164同样受到锁止元件开口1113的限制而只能横向向内收缩，锁止齿条2168与运动夹持元件齿条1125脱离，从而解除锁止运动夹持元件112。
锁止机构216的锁止状态如图10所示，锁止元件2161的中部2163在锁定控制杆1154的作用下纵向向下移动，由于锁止元件2161的端部2164同样受到锁止元件开口1113的限制而只能横向向外扩张，锁止齿条2168与运动夹持元件齿条1125啮合，从而将运动夹持元件112锁止。
以上详细说明了根据本发明的优选实施例的夹持装置11的结构，相应地，与该夹持装置11相连的悬臂12的结构可以根据需要进行调整，在此并不做进一步限定，该悬臂12只要能够将该夹持装置11连接于基座2并实现本发明的目的即可。当然，夹持装置11和悬臂12的具体连接方式也可以根据需要进行调整，现有技术中凡是能够将两者连接起来的元件都可考虑用于本发明中。为了更好地实现本发明的目的，以下仅提供一种具有上下翻转和左右移动功能的连接机构作为示例，该连接机构14包括上下翻转机构141和铰链机构142。
图11-图12示出了根据本发明的第一实施例的车载支架系统的设备支架的连接机构的上下翻转机构，该上下翻转机构141包括夹持装置后盖1411、螺栓衬套1412、铰链外壳1413和螺栓螺母1414，其中，夹持装置后盖1411固定于夹持装置11，例如固定于固定夹持元件111的背面，螺栓衬套1412设置于夹持装置后盖1411与夹持装置11之间，而螺栓螺母1414依次贯穿螺栓衬套1412、夹持装置后盖1411和铰链外壳1413，该螺栓螺母1414的自由端通过垫片和法兰螺母旋紧。具体地，夹持装置后盖1411的中部为具有开口的横置的薄壁圆柱形，其内外壁分别与螺栓衬套1412的后表面及铰链外壳1413的前表面贴合。螺栓衬套1412的中部具有定位凸台，铰链外壳1413的中部具有定位沉台，螺栓衬套1412的定位凸台穿过夹持装置后盖1411中部的开口与铰链外壳1413的定位沉台紧配合。当螺栓螺母1414锁紧时，螺栓衬套1412与铰链外壳1413对被其压紧在中间的夹持装置后盖1411的圆柱面施加摩擦力，如此，夹持装置11相对铰链外壳1413获得有摩擦锁止的上下翻转功能。如图12所示，夹持装置后盖1411的转动中心1415位于运动夹持元件112的表面，即待加持设备(例如手机)的背侧。夹持装置后盖1411中部的开口与螺栓衬套1412的定位凸台上下表面之间各有一定间隙，从而允许夹持装置后盖1411以转动中心1415进行一定角度范围内的上下翻转。
图13-图14示出了根据本发明的第一实施例的车载支架系统的设备支架的连接机构的铰链机构，该铰链机构142包括悬臂轴瓦结构1421、C形卡环1422和铰链轴销1423，其中，悬臂轴瓦结构1421固定于悬臂12，例如固定 于悬臂12的前端位置，铰链轴销1423固定于铰链外壳1413，悬臂轴瓦结构1421本身由彼此对称的半部形成，铰链轴销1423容置于该悬臂轴瓦结构1421内，而C形卡环1422围绕着该悬臂轴瓦结构1421设置。具体地，C形卡环1422由金属制成，其内径略小于悬臂轴瓦结构1421的外径，当C形卡1422环套于悬臂轴瓦结构1421外时，会向悬臂轴瓦结构1421施加抱紧力，当铰链轴销1423穿入悬臂轴瓦结构1421时，所述抱紧力作用在铰链轴销1423与悬臂轴瓦结构1421之间，使铰链轴销1423获得转动方向的摩擦锁止力。由于铰链轴销1423与铰链外壳1413之间设置为防转键槽配合，因此铰链外壳1413可以与铰链轴销1423一同相对悬臂12有摩擦锁止地转动。
以上所述的，仅为本发明的较佳实施例，并非用以限定本发明的范围，本发明的上述实施例还可以做出各种变化。即凡是依据本发明申请的权利要求书及说明书内容所作的简单、等效变化与修饰，皆落入本发明专利的权利要求保护范围。本发明未详尽描述的均为常规技术内容。
